Ah, that helps, thanks. It is completely fine -- I am just pointing it
out in case it helps you make this easier to land and for others to
follow.

Yeah, the branch is definitely nice to have to see the end state you
want, but having the Lore links helps a lot clarifying what the
dependencies (and their version etc.) are. You can use that chance to
mention anything out of the ordinary for each dependency (e.g. like
you mentioned here).

I would suggest using `checkpatch.pl` with `--codespell` (I don't know
if it catches this one -- I just saw it in my client -- but their
dictionary definitely did catch some for us in the past).

I have some notes at:

    https://docs.kernel.org/rust/coding-guidelines.html#lints

Generally speaking, we default to `expect` unless there is a reason
not to (I list some possible reasons in the link), because `expect`
forces us to clean it when unneeded.

Not sure what you mean by "development phase" -- even if Tyr is under
development, it should still try to conform to the usual guidelines.
Of course, if a particular `expect` would be a pain, then please feel
free to use `allow`. But is that case here? i.e. you will want to
remove the `allow` anyway when you add the new code, no?

Thanks!

Cheers,
Miguel
